Glaucoma is one of the leading causes of blindness worldwide, and vision loss, due to the loss of retinal ganglion cells (RGCs), cannot currently be reversed with any treatment. Some studies have looked at replacing RGCs through cell transplants, but this process is still in the research and development stage and fraught with limitations that highlight a need for a more precise manner of effectively repopulating these cells in the retina.
